Priority: high Milestone:
Component: kernel Version:
Keywords: memory leak on madwifi in ad-hoc Cc:


think that there is a memory leak on madwifi driver ( i've tested r2420 and r2568 package). I use kamikaze 7.07 rev 8078 with kernel 2.6.22. after 1 or less hours my aps is freezed (if i connect with serial console i look "no enough memory" ) sad( i've look this problem on Meraki mini and on RouterBoard 133 (this with 3 radios).

i'use this board for mesh network in Ad-hoc mode and with fixed rate to 11M.

anyone have idea to Solve/workaround?
